Cyber-attacks against Industrial Control Systems (ICS) can lead to catastrophic events which can be prevented by the use of security measures such as the Intrusion Prevention Systems (IPS). In this work we experimentally demonstrate how to exploit the configuration vulnerabilities of SNORT one of the most adopted IPSs to significantly degrade the effectiveness of the IPS and consequently allowing successful cyber-attacks. We illustrate how to design a batch script able to retrieve and modify the configuration files of SNORT in order to disable its ability to detect and block Denial of Service (DoS) and ARP poisoning-based Man-In-The-Middle (MITM) attacks against a Programmable Logic Controller (PLC) in an ICS network. Experimental tests performed on a water distribution testbed show that, despite the presence of IPS, the DoS and ARP spoofed packets reach the destination causing respectively the disconnection of the PLC from the ICS network and the modification of packets payload.

El inter{\'e}s actual por desplegar infraestructuras de carga de veh{\'\i}culos el{\'e}ctricos para el ahorro energ{\'e}tico y la sostenibilidad es cada vez m{\'a}s palpable, lo que llama la atenci{\'o}n a muchas comunidades, especialmente a la cient{\'\i}fica, para explorar, entre otras cosas, la influencia de las nuevas tecnolog{\'\i}as de informaci{\'o}n en los procesos operacionales. Teniendo en cuenta este escenario, este art{\'\i}culo, por tanto, analiza c{\'o}mo el uso de los sistemas de multi-agente pueden beneficiar las tareas de monitorizaci{\'o}n, mantenimiento y de seguridad, y propone una arquitectura espec{\'\i}fica en base a los actores especificados en el protocolo OCPP (Open Charge Point Protocol). Esta arquitectura constituye la base para analizar los diversos tipos de amenazas que agentes software pueden sufrir, clasific{\'a}ndolas de acuerdo a las caracter{\'\i}sticas funcionales e interacciones con los diversos elementos de la infraestructura. Esta agrupaci{\'o}n y el conjunto de ataques abordados est{\'a}n basados en el SP-800-19 definido por el National Institute of Standards and Technology, y formalizados siguiendo la metodolog{\'\i}a de {\'a}rboles de ataque. El estudio revela la importancia que tiene analizar los riesgos que esta tecnolog{\'\i}a puede traer a este escenario, proporcionando, adem{\'a}s, un conjunto de recomendaciones que sirvan de gu{\'\i}a para aplicaciones futuras.

Migration to an electronically controlled electrical grid to transmit, distribute, and deliver power to consumers has helped enhance the reliability and efficiency of conventional electricity systems. At the same time, this digitally enabled technology called the Smart Grid has brought new challenges to businesses and consumers alike. A key component of such a grid is the smart-metering technology, which is used to collect energy consumption data from homes and transmitting it back to power distributors. A crucial concern is the privacy related to the collection and use of energy consumption data. We present an analysis of Smart Grid privacy issues and discuss recently proposed solutions that can protect the privacy of Smart Grid users.
